MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed April 24, 1908. Serial No. 428,905.

To all whom it may concern:

Be it known that I, SAMUEL JoNEs, a citizen of the United States, and aresident of East Liverpool, in the county of Columbiana and State ofOhio, have invented a new and Improved Mechanical Movement, of which thefollowing is a full, clear, and exact description.

The invention relates to mechanical movements for converting continuousrotary motion in one direction into alternate forward and backwardrotary motion.

The object of the invention is to provide a new and improved mechanicalmovement for use on washing machines, churns and like machines, andarranged to automatically revolve a part of the machine a predeterminednumber of times alternately in opposite directions and with the use ofonly a single driving belt.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this speclfication, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is an end elevation of the improvement as applied to a washingmachine; Fig. 2 is a longitudinal central section of the same on theline 2-2 of Fig. 1 showing the gearing in elevation; Fig. 3 is alongitudinal sectional elevation of the same on the line 33 of Fig. 1Fig. 4 is a transversesection of the improvement on the line 44 of Fig.2, and Figs. 5 and 6 are side and end views respectively of the beltshifter.

In the casing A of the Washin machine is mounted to rotate the cylinderhaving its shaft B extending through one end of the casing A, asindicated in Fig. 2, and on the outer end of the said shaft B is secureda gear wheel C in mesh with pinions D and E, of which the inion D issecured or formed on the hub of a loose pulley F mounted to turn looselyon a shaft G journaled in suitable bearings, of which one is in the endof the casing A and the other in a bracket A attached to the casing A.The pinion E is secured on a shaft E journaled in the casing A and thebracket A, and on the said shaft E is secured a gear wheel E in meshwith a car wheel E attached to or formed on the hu of another loosepulley H mounted to rotate loosely on the shaft Gr.

Between the loose pulleys F and H is arranged a driving pulley I securedon the shaft G and this driving pulley I is at all times engaged by abelt J adapted to be partly shifted alternately onto the loose pulleys Fand H, so as to rotate the same, at the same time, however, keeping upthe rotary motion given to the ulley I and its shaft G. Now when thebelt J is in engagement with the pulley H, the cylinder B is rotated inone direction by the gear wheels E E shaft E,

inion E and the gear wheel O, and when the belt J is-shifted onto thepulley F the latter is rotated so as to turn the cylinder B in thereverse direction by the pinion'D and the gear wheel O.

The belt J is partly shifted from the pulley I alternately onto thepulleys F and H by a belt-shifting mechanism actuated from thecontinually driven shaft G, and for this purpose the followingarrangement is made: The belt J is engaged by a belt shifter K havingits rod K provided with a hub K held on a shifter rod L between collarsL and L as plainly indicated in Fig. 3. The shifter rod L is mounted toturn and to slide in suitable bearings arranged on a bracket A formingpart of the bracket A, and on the shifter rod L is arranged a handle Lunder the control of the operator.

On the shifter rod L is secured an arm N adapted to extend betweencollars O, 0 secured on a slide 0, mounted to slide longitudinally onthe bracket A parallel to the rod L. The collar 0 is provided with aslotted arm 0 engaged by a wrist pin 1? held on the face of a worm wheelP journaled in suitable bearings arranged on the bracket A The wormwheel P is in mesh with a Worm P secured on the driven shaft G, so thatthe rotary motion of the shaft G is transmitted by the worm P to theworm wheel P, which by the wrist pin P acting on the arm 0 causes acontinuous forward and backward motion of the slide 0, so that the arm Nis carried along and with it the shifter rod .L and shifter to shift thebelt J alternately onto the pulleys F and H, as previously mentioned.

The gearing is so proportioned that the shifting of the belt J takesplace whenever the cylinder B has made say three revolutions, that is,after threerevolutions in one direction the belt is shifted so that thecylinder B is rotated three times in theopposite direction, and so on.When it is desired to stop the machine, the operator swings the handle Lover so as to swing the arm N out of engagement with the collars 0, Oand then the operator shifts the rod L in the di rection of its lengthand engages the arm N with a fork Q attached on the bracket A When thistakes place the belt J is in engagement with the driving pulley I only,and is held'in this position, it being'understood' that although theslide 0 keeps up'its movement it does not actuate the rod L, as thearm Nis out of engagement with the'collars 0, O and hence the belt is notshifted.

In practice, it is desirable to make the driven pulley I somewhat widerthan the loose pulleys F and H and to use the belt J having a Widthcorresponding approximatelyto that of the pulley I, so as to read ilyengage the pulley I and at thesame-time either pulley F or H.

The mechanical movement shown and described is very simple and durablein construction, and composed of comparatively few parts, not liableeasily to'get out of order. Having thus described -my invention, I

claim as new and desire to secure byLetters Patent:

1. A mechanical movement comprising a shaft, a-driving'pulley securedthereon, loose pulleys on the said shaft on opposite sides of the saiddriving pulley, gearings connecting the said loose pulleys with the partto be driven, a driving belt for the said pulleys, and an automaticbeltshifter for the said belt and actuated from thesaid shaft.

2. A mechanical movement comprising 'ashaft, a driving pulley securedthereon,'loose pulleys on the said shaft on opposite sides of the saiddriving pulley, gearings connecting the said loose pulleys with the partto be driven, a driving belt for the said pulleys, a belt shifter forthe said belt, and an actuat- ,ing mechanism connecting the'said shaftshaft, a driving pulley secured-thereon, loose pulleys on the said shafton opposite sides of the said driving-pulley, gearings connecting thesaid loose pulleys with the part to be driven, a driving belt for thesaid pulleys, a belt shifter mounted to slide and engaging the-saidbelt, a slide engaging the'said belt shifter for shifting the latter, aworm wheel having a wrist'pin engaging the said slide, and a worm on thesaid shaft and in mesh with the said worm wheel. v

4. A mechanical movement comprising a shaft, a driving pulley securedthereon, loose pulleys on the said shafton' opposite sides of the saiddriving pulley, gearings connecting the said loose pulleys with thepartto be driven, adriving belt for the said pulleys, a"
